Getting rid of the Google sign in box all over the web

I've been increasingly annoyed by the "Sign in with Google" box showing up on a lot of websites. Not only is it yet another thing to dismiss when arriving on a website. It also tells Google which websites I visit.

Today I took the time to find out how to get rid of it. And it can be removed by manually adding a single new filter to uBlock Origin in Firefox:

||accounts.google.com/gsi/*$xhr,script,3p
